Tool Information
Datasette ChatGPT Plugin is an open-source extension that exposes a Datasette instance for natural-language questions through a ChatGPT-compatible plugin interface. Developers should use read-only least-privilege databases, exclude sensitive tables, secure authentication and hosting, inspect generated SQL, rate-limit access, test hallucinations and query cost, keep audit logs and retain human verification.
Use authorized, minimal inputs and grant integrations the least access required. Configure privacy, retention, sharing, quality, accessibility, disclosure, export, governance, moderation and spending controls. Test representative cases, verify generated facts, calculations, citations, code, queries, model output and visual details, preserve originals and version history, and retain accountable human approval before publication, deployment or operational action.
The plugin is free and open source. Datasette hosting, database infrastructure, model access, authentication, monitoring, maintenance and development may create separate costs.
AI output can be inaccurate, biased, derivative, insecure, incomplete or misleading. Review consent, copyright, commercial rights, training and retention terms, renewals, refunds, platform rules and applicable law. Database, analytics, finance, healthcare, computer-vision, customer-service and enterprise workflows require qualified human review.
